Power Consumption

Our exploration of power consumption begins with a look at the Strix RX 570 OC as it performs different tasks.

Similar to Radeon RX 580, AMD introduced an intermediate memory clock state so that the GDDR5 doesn’t have to run at full speed with multiple monitors attached or while playing back video content. So long as your displays are set to the same resolution, this approach works just as well for Radeon RX 570.

When it comes to gaming, though, the card breaks out of its shell. A 30 MHz-faster GPU and a higher memory clock rate result in an additional 13W of power consumption. Our stress test looks even worse, maxing out the 200W power limit. These numbers show that Asus tries to do a better job stabilizing its boost frequency compared to last generation’s version by increasing the card’s power limit.

The average voltage measured during our extended test is 1.15V. That’s 0.15V more than Asus’ Strix RX 470 OC, and now you know how the newer card’s higher frequency is hit and kept stable.

In the end, the older Strix RX 470 OC’s 1270 MHz ceiling was more of a fantasy. Asus’ RX 570 version makes higher frequencies an achievable reality.

A Closer Look

Our gaming and stress test power consumption curves are quite different. Even though the gaming measurements peak as high as 225W, average power consumption in this workload is relatively low.

The stress test registers significantly higher power use due to a more consistent load, which pushes the Strix RX 570 OC to its 200W limit.

Balancing Power Consumption

Our discussion comes back to the voltage regulator’s three phases, and how that configuration relates to the current on each rail.

The motherboard slot experiences peaks of up to 6A, which exceed the PCI-SIG’s specifications by 0.5A. At 5A, though, our calculated average ducks in below the consortium’s 5.5A ceiling. Six real power phases would have allowed for more control over the distribution, making it possible to avoid this imbalance.

Our measurements rise during the stress test. An average of 5.6A now exceeds the PCI-SIG’s 5.5A limit. Of course, as we know from AMD’s reference Radeon RX 480 (and the subsequent tests we were compelled to run, proving our initial observations), that doesn’t mean your motherboard will catch on fire. But it also doesn’t bode well for overclocking, particularly on older platforms.

The following bar graph provides a general overview of the results:

When you don’t have the key, a crowbar will do. Rather than following up Radeon RX 470 with finesse, the company figured out a way to coax higher clock rates out of Ellesmere by increasing the GPU’s voltage.

How to Choose a Power Supply for the RX 570 GPU

The main job of a power supply is to convert the alternating current (AC) from your wall outlet into the direct current (DC) needed by the components inside your computer.

Power Output

An important factor when buying a PSU is the supported wattage.

You will need to add up the power consumption of each computer component to determine the total output power requirements for your power supply.

The peak power consumption of AMD’s Radeon RX 570 GPU is 150 W.

You can estimate your power requirements by using the following chart.

Component Peak Power Usage
RX 570 GPU 150 W
Top-Tier CPU (e. g., Intel Core i9 13900K) 253 W
Mid-Tier CPU (e.g., Intel Core i5 13600K) 181 W
Motherboard 80 W
Optical Drive 30 W
3.5″ Hard Drive 9 W
M.2 or 2.5″ SSD 9 W
140 mm Case/CPU Fan 6 W
120 mm Case/CPU Fan 6 W
80 mm Case/CPU Fan 3 W

By adding up these numbers, you can estimate peak power usage. Check out the top-tier and mid-tier example builds below.

It’s generally a good idea to add a 100–150 W buffer to your expected usage. This buffer will give you some flexibility in case of miscalculations and will allow you to add more drives, fans, or add-in cards in the future.

In most cases, buying a little more wattage than you need is a safer choice for ensuring system stability.

Don’t forget to account for the additional power required for overclocking if you intend to overclock your CPU or GPU. Overclocking could require roughly an extra 50–100 W, depending on how much you overclock these devices.

Power Efficiency

PSUs with higher efficiency ratings use less energy and produce less heat, improving their reliability and reducing noise.

The 80 PLUS certification program for power supplies helps to promote energy efficiency by indicating its efficiency rating.

Higher efficiency power supplies may have a higher upfront cost. However, they could potentially save you money on electricity in the long run.

Lower wattage PSUs will be more power-efficient even when idle. For this reason, you may be able to save more on electricity by getting the correct wattage of PSU than by getting the one with the best 80 PLUS rating.

PSU Efficiency Levels (115 V)
Certification Level 10% Load 20% Load 50% Load 100% Load
80 Plus 80% 80% 80%
80 Plus Bronze 82% 85% 82%
80 Plus Silver 85% 88% 85%
80 Plus Gold 87% 90% 87%
80 Plus Platinum 90% 92% 89%
80 Plus Titanium 90% 92% 94% 90%

Cables

Connectors

Make sure your PSU has the correct connectors to support the hardware in your system. Cheaper PSUs may cut costs on connectors and cables by offering fewer options and shorter lengths.

Check with your motherboard and graphics card documentation to determine which connector types are needed. Buy a popular, recently-released PSU; it will likely have the necessary connectors for a new PC build. However, if you use old components or an old power supply, you may find some incompatibilities.

Here are some common connector types that power supplies support:

  • 24-pin connector for the motherboard
  • 4/8-pin connector for the CPU
  • 6/8/16-pin connectors for graphics cards
  • SATA Power connector for each SATA HDD or SDD storage device

The latest graphics cards and ATX 3.0 PSUs support a new 16-pin PCIe 5.0 connector that replaces multiple 8-pin connectors.

Modular Cables

Typical power supplies come with various cables to connect your components. However, extra unused power cables can work against you by interrupting airflow.

In comparison, modular and semi-modular power supplies allow for attaching only the cables you need. As the name implies, semi-modular power supplies have some wires soldered on, while you can optionally connect others.

Cable Lengths

Most power supplies will have cables long enough to support mid-sized towers comfortably. If you have a full-size tower, you may want to check reviews and documentation to ensure that the cables are long enough to allow good cable management.

Power Supply Form Factors

Various form factors are available for power supplies. However, a standard-size desktop PC build will use an ATX power supply.

Small form factor PSUs allow for usage in many computer case shapes, including mini-PCs.

Power Supply Features

Overvoltage protection and short circuit protection can help to save your components in the case of a surge or accident.

LED lighting is another feature you might consider, depending on your PC goals.

Choosing a Cost-Effective Power Supply for the RX 570

Perhaps you live in a dorm or a family member’s house and don’t pay the power bill. Or maybe you don’t expect the computer to have heavy daily usage. In those cases, the lower upfront cost of a less efficient PSU may be the better choice.

On the other hand, if you care more about the electric bill or the environment and plan to maintain higher CPU or GPU usage, then a more efficient PSU may be better.

Don’t go too far over 150 W above your expected power needs. Rightsizing your power supply will keep electricity costs to a minimum, as higher wattage PSUs will consume some additional power, even when idle.
